Answer:
the first one
the third one
and the forth one
Step-by-step explanation:
they all add up to the same amount
According
to the empirical rule, if the data form a "bell-shaped" normal
distribution, approximately 99.7 percent of the observations will be contained
within 3 standard deviations around the mean.

To add, a bell curve is used to describe the mathematical concept called
normal distribution, sometimes referred to as Gaussian distribution. </span>
Answer:
me too
Step-by-step explanation:
Answer:
x= −1/2, x=52/5
Step-by-step explanation:
2(x+7)=13
(2)(x)+(2)(7)=13(Distribute)
2x+14−14=13−14
2x=−1
2x/<u><em>2</em></u>=−1/<u>2</u>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
5(x−7)=17
(5)(x)+(5)(−7)=17(Distribute)
5x+−35=17
5x−35=17
5x−35+35=17+35
5x=52
5x/<u><em>5</em></u>=52/<u>5</u>
Answer:
1- click
2--trick
3- track
4-trace
Step-by-step explanation:
equation (y=x+2) x y
y=-3+2 -3 -1
y=-1+2 -1 1
y=0+2 0 2
y=2+2 2 4
you can plot the points ( click)
<h2>equation (y=-x) x y</h2>
y=-(-2) -2 2
y=0 0 0
y=-1 1 -1
y=-3 3 -3
plot the points
<h2>equation (y=1) x y</h2>
y=1 no matter what the value of x -3 1
(-3,-1,0,2) -1 1
0 1
2 1
<h2>y=1/2 x +1 x y</h2><h2> y=-4/2 +1 -4 1</h2>
y=-2/2 +1 -2 0
y=1/2(0)+1 0 1
y=3/2 +1 3 2.5
